VARIETY DENOMINATION

‘ANP-0131’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of pear tree named ‘ANP-0131’. My new tree resulted from a planned hybridization program and is a selection from crossing ‘Corella’ (Unpatented) as the seed parent with ‘Doyenne du Cornice’ (Unpatented) as the pollen parent. The resulting tree was selected when growing in a cultivated area in Goulburn Valley, Australia.

BRIEF SUMMARY OF THE INVENTION

The ‘ANP-0131’ variety is distinguished from other pear varieties due to the following unique combination of characteristics: bicoloured fruit with a strong red blush over a green colored skin; fruit ripen to a fine texture low in grit and can be eaten either firm or softened to a desired firmness and the fruit can be stored long term without loss in eating quality.

Asexual reproduction of this new variety by grafting and budding onto rootstock (D6 and Quince A) shows that the foregoing characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations.

The following detailed description concerns the original tree, selected on January 2001, and progeny first asexually propagated in 2003. The original tree and progeny have been observed growing in a cultivated area in Goulburn Valley, Australia.

Certain characteristics of this variety may change with changing environmental conditions (such as photoperiod, temperature, moisture, soil conditions, nutrient availability, or other factors). For example, leaf colors may be brighter green if the trees are grown in soil with greater nitrogen concentrations, and may be more yellow when grown in soil containing lesser amounts of nitrogen. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations (hue/value/chroma) are made with reference to The Royal Horticultural Society Colour Chart (R.H.S.).

The color photographs show typical specimens of the leaves and fruit of this new pear tree variety and depict the color as nearly true as is reasonably possible to make the same in a color illustration of this character. It should be noted that colors may vary, for example due to lighting conditions at the time the photograph is taken.

Therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the photographs alone.

DETAILED DESCRIPTION Botanical

The following detailed description of the ‘ANP-0131’ variety is based on observations of asexually reproduced progeny. The observed progeny are trees which were 10 years of age and growing on D6 (Pyrus calleryana) variety rootstock in Goulburn Valley, Australia.
